The Associated Press reported that Eustaquio struck late after South Africa failed to clear a cross, turning a tight round-of-32 match into Canada's first appearance in the last 16. ESPN also reported the 1-0 scoreline and the stoppage-time goal, while the Guardian's match report described Canada as the first team through to the last 16.
For Canada, the result is a threshold rather than a performance manifesto. Jesse Marsch's side did not sweep South Africa aside. It stayed in the game, waited for one loose defensive action, and took it. That is often what knockout football asks for, but it also sets the limits of the lesson: resilience was enough on Sunday; it may not be enough against a stronger opponent.
The goal was still a clean tournament moment. AP reported that Eustaquio's strike came after 90 minutes in which Canada had struggled to break through. The scoreline turned on execution rather than volume. Canada had the territorial emotion of a co-host and the burden of trying to turn a favourable draw into a first historic step. South Africa kept the match narrow enough that extra time was visible until the final minutes.
Marsch made the milestone explicit after the whistle. AP reported that he gathered his players on the pitch and told them they were "Canadian heroes" for the future of the sport in the country. It was an emotional reaction, but the sporting fact underneath it is straightforward: Canada had never before won a World Cup knockout match.
South Africa's exit is harsher than the scoreline suggests. A one-goal defeat in stoppage time does not read like a team outclassed. It reads like a side that defended long enough to be close to another half-hour and then paid for one late breakdown. That is not consolation, but it is a fairer account than treating Canada's landmark as proof of a one-sided match.
